    Abstract: The present application relates to a dual energy detector and a radiation inspection system. The dual energy detector comprises: a detector module mount and a plurality of detector modules. The detector module includes a higher energy detector array and a lower energy detector array, which are juxtaposedly provided on said detector module mount to be independently irradiated. The present application may simplify the arrangement of the photodiodes and printed circuit boards to which the higher and lower energy detector arrays are connected, such that necessary thickness dimension of the detector module mount is reduced, thereby facilitating the installation and use of the dual energy detector of the present application. On the other hand, the radiation beam in the present application may be independently irradiated to the higher and lower energy detector arrays juxtaposed to each other, which reduces to certain extent the mutual restriction during selection of the higher and lower energy detector arrays.

    Abstract: The present disclosure discloses an afterglow detection device and an afterglow detection method. The afterglow detection device comprises: an X-ray tube for emitting an X-ray beam; a first reading circuit for receiving a first detected signal from a to-be-detected detector to form and output a first measurement signal according to the first detected signal, the to-be-detected detector being connected to the first reading circuit and disposed on a beam-out side of the X-ray tube to receive radiation of the X-ray beam and outputting the first detected signal to the first reading circuit at the time of detection; a residual ray detector disposed on a beam-out side of the X-ray tube; a second reading circuit connected to the residual ray detector for receiving a second detected signal from the residual ray detector to form and output a second measurement signal according to the second detected signal.

    Abstract: A large-area X-ray gas detector includes a housing having an inner cavity and a ray entrance communicated with the inner cavity, a thin entrance window and a signal collection module. The inner cavity is filled with a working gas which is a non-electronegativity gas sensitive to the X-ray. The entrance window is hermetically connected to the ray entrance such that the X-ray enters into the inner cavity. The signal collection module comprises an anode wire electrode layer and a cathode electrode layer arranged parallel with each other in the inner cavity, in which the anode wire electrode layer has an anode wire for accessing to a high voltage, and the cathode electrode layer is grounded. The anode wire electrode layer collects electrons generated by the working gas under an action of the X-ray.
